About this project
Hello everyone, apologies for not reaching our funding goal - this time. Thank you to those of who contributed, we appreciate your support. To keep yourself updated on our next move …
Save fuel, save money, save the world
Ecorithmic is an automatic ecodriving system that is fitted into a smartphone app. It will help you to perform ecodriving while driving your car. Through the smartphone sensors, and the library of ecodriving parameters, the ecorithmic app will work out how to drive in a fuel-efficient and environment friendly way. Through the use of the ecorithmic app, you could reduce your fuel consumption by up to approximately 15%. This means, you save not only your money, but more importantly, our world as well.
What is ecodriving
Ecodriving means driving a motor vehicle in a fuel efficient way. There are many different ways to do so. Our focus is how to utilize the stored mechanical energy in the vehicle. Mechanical energy is the energy stored in the vehicle due to its speed (kinetic energy) and its altitude (potential energy). The kinetic energy can move the car forward without the engine, and the potential energy can be converted to kinetic energy by rolling down a slope.
How to use it
Let’s say you are about to drive your car to your work. When seated, you start your ecorithmic app, select the pre-recorded route to your place of work and start driving. The ecorithmic app now continuously measures your mechanical energy and uses the information stored about the pre-recorded route to calculate when to start rolling the car. By doing so, you are using the mechanical energy stored in your vehicle instead of using the engine to move the car forward.
The greener the better
Rolling your car can be done in different ways depending on your type of car. If your car has a manual transmission, you could just put the car in neutral while driving. If your car has an automatic transmission, you could take your foot off the gas pedal. Rolling the car could, for instance, be done when you approach a traffic sign, that shows a lower speed limit. Your car then gradually slows down until you reach the correct speed as you pass the speed sign. And, while driving, the ecorithmic app will use voice commands to tell you when to start to roll your car and when to resume normal driving.
Advance signal processing is applied to the data of the smartphone sensors
There are many reasons to roll your car, e.g. to gradually slow down as you approach a stop sign, traffic light, speed bump or to reach a safe speed for an upcoming turn. Downhill slopes are used to convert your potential energy to kinetic energy by rolling down the slope. The ecorithmic app will track any combination of slopes, traffic signs, speed bumps and so on, and will optimize your actions for a comfortable and environment friendly drive.
How to record a route
By recording a route we mean gathering all of the information about the route needed for the ecorithmic app. Assume that you are about to record your route to work. First you would need to record the route geometry, which means recording the route in three dimensions, latitude, longitude and altitude. This captures the information of the turns and slopes in the road along your chosen route. While recording the route geometry, the smartphone needs to be fixed inside the car. This is done by placing the smartphone on a sticky pad on the dashboard.
Place the smartphone on the sticky pad when measuring the route geometry
Once the route geometry has been recorded, you can add any other information to your route, such as the location and speed limit of speed signs, traffic lights, speed bumps or anything else you think would affect your choice of speed. This is again done through recording.
Click the related icon as you pass a speed bump, stop sign etc.
To add route parameters, simply drive the route again, and click the related icon on the app as you pass a speed sign or a speed bump. The symbol and its position will be stored as route parameters in the app. This can be done in steps, and at first perhaps you would record all speed limits, followed by all traffic signs the next time you drive the route and so on. The greater the number of parameters you add, the more fuel you can save. While recording these route parameters, the smartphone does not need to be fixed inside the car. However, a car mount holder may be helpful.
If you are not happy with the data you recorded, you can edit the recorded parameters of your route manually. For example, you can change the location or the speed limit of a speed sign. You can also add or delete any other route parameters.
Select the best choice of signs for your country.
Our technology works with any android smartphone or tablet. You will need to install our app, and you are ready to go. The app will work for any type of car, and with a simple procedure you can calibrate the app to your car’s dynamic properties.
The app and your smartphone form a multi-sensor system, which applies advance algorithms to the data collected by your smartphone sensors. One critical sensor is the GPS, which usually does not work inside tunnels or similar structures. During these times the ecorithmic app will pause.
We need your help
Over the past couple of years, the advance signal processing of the ecorithmic app has been developed as an ad hoc project. To turn this into a finished product, we need your support to complete the final details. We believe the ecorithmic app is attractive to a lot of people, and we are using this process to see if this is true.
We are sorry to say that an iPhone version of our app will not be available via our Kickstarter project. However, please look us up on Facebook or on our website for updates on availability in the App Store.
At present we have a lab version of the app, with the final commercial version yet to be developed. If we were to receive adequate funding, we would start work immediately, with the goal to have a commercial version of the app completed by the beginning of next year.
A few last words for our world
You have probably heard it many times before; global warming, melting glaziers, thawing tundra, and drowning polar bears. Maybe you feel that not enough is being done to combat environmental issues, and that you would do more if you only could. A substantial part of the world’s CO2 emissions come from cars, trucks and busses. If we could all lower our fuel consumption by 15%, it would help.

Risks and challenges
Throughout the years, I have learned to respect the difficulties one has to deal with while working with sensor systems. For instance, it may seem like a trivial task to measure altitude by using the altitude measurements given by the GPS in the smartphone. But anyone who has tried will know that it is not. This is why we use multi-sensor techniques to solve our measurement problems; in addition, all algorithms have been thoroughly tested on real measurements and in real time.
I have worked as an algorithm development consultant for many years, and have had the responsibility for project management and time planning. This project is not different from other projects I have been involved in; except the fact that this project is a lot more fun.
We will continue to improve our methods and test our algorithms further, add functionality, and improve performance of the app through software upgrades.
